Description
Technical field
The invention belongs to technical field of processing fuel oil, relate in particular to a kind of additive and high-grade gasoline thereof that utilizes petroleum naphtha to produce high-grade gasoline.
Background technology
Petroleum naphtha is the straight run low octane value gasoline in the oil refining process, is called petroleum naphtha abroad, and the domestic raw gasline that is called is a kind of colourless transparent liquid, one of through-stone oil distillate has alkane, naphthene content height, and roadholding is good, heavy metal content is low, and sulphur content is low, the toxicity features of smaller.Petroleum naphtha is generally the lighting end that crude oil steams under certain conditions through fore-running, air distillation, or secondary processing of gasoline through tame hydrogen refining and gasoline fraction, boiling range generally is an initial boiling point to 220 ℃.Petroleum naphtha is generally as the raw material of producing ethene or aromatic hydrocarbons, with traditional petroleum refining technology catalytic reforming it is processed into high-grade gasoline and needs very high cost consumption, simultaneously because the chemical property of petroleum naphtha, all petroleum naphtha is not directly used as gasoline both at home and abroad, so utility value is not high.China is consumption of petroleum big country, and is particularly more nervous to the fuel gasoline demand, and the comprehensive utilization petroleum resources are that technical problem to be solved is arranged always.
At present, adopt traditional refining of petroleum device or hydrogenation gas method that petroleum naphtha is processed into high-grade gasoline both at home and abroad, the promptly dangerous cost that increases again needs under the condition of high pressure and hydrogenation catalyzer added and refines out high-grade gasoline in the petroleum naphtha.
Summary of the invention
The purpose of this invention is to provide a kind of physical mixed of under normal temperature and pressure conditions, passing through, utilize petroleum naphtha to produce the additive and the high-grade gasoline thereof of high-grade gasoline.
The technical solution used in the present invention is as follows:
A kind of additive that utilizes petroleum naphtha to produce high-grade gasoline is characterized in that this additive is made up of following weight percentages: Nitromethane 99Min. 25～40%, methyl alcohol 20～30%, pimelinketone 8～10%, Monoethanolamine MEA BASF 1～2%, ethylene glycol monomethyl ether 30～45%.
This additive can specifically be made up of following weight percentages: Nitromethane 99Min. 35%, methyl alcohol 26%, pimelinketone 7%, Monoethanolamine MEA BASF 1%, ethylene glycol monomethyl ether 31%.
Described petroleum naphtha is the petroleum naphtha of research octane number (RON) between 48～65.
A kind of high-grade gasoline that utilizes petroleum naphtha to add Additive Production, the weight percent that it is characterized in that each raw material in this high-grade gasoline consists of petroleum naphtha: catalyzer=60～75: 25～40, and described additive is made up of following weight percentages: Nitromethane 99Min. 25～40%, methyl alcohol 20～30%, pimelinketone 8～10%, Monoethanolamine MEA BASF 1～2%, ethylene glycol monomethyl ether 30～45%.
Described petroleum naphtha is the petroleum naphtha of research octane number (RON) between 48～65.
The Nitromethane 99Min. of described additive, methyl alcohol, pimelinketone, Monoethanolamine MEA BASF, ethylene glycol monomethyl ether are commercially available technical grade product, are industrial anhydrous raw material.For example the manufacturer of described Nitromethane 99Min. has: Nantong is contained safe chemical industry company limited, Shandong Bao Yuan chemical industry company limited, source, Shanghai and is got over chemical industry company limited; Described methanol production producer has: Lanzhou fertilizer plant of chemical industrial company, Resins, epoxy factory of Ba Ling petro-chemical corporation, Sichuan vinylon plant; Described Cyclohexanone Production producer has: two factories of Shanghai Gaoqiao petrochemical corporation (complex), good big chemical industry company limited, west, the Guangzhou Gansu Province chemical reagent company limited of reaching in Guangzhou; Described ethylene glycol monomethyl ether manufacturer has: auspicious good chemical industry company limited of Yida Chemical Co., Ltd. Jiangyin, Jiangsu, Jiangsu Tianyin Chemical Industry Co., Ltd.
This additive can by above-mentioned five kinds of raw materials by weight ratio physical mixed make, its blending means can be: with technical grade purity is that 99% Nitromethane 99Min. joins to mix in the industrial methanol and obtains intermediate product, pimelinketone, Monoethanolamine MEA BASF and ethylene glycol monomethyl ether mixed obtain another intermediate product, above-mentioned two kinds of intermediate products are mixed, promptly obtain utilizing petroleum naphtha to produce the additive of high-grade gasoline.
Utilize method that petroleum naphtha produces high-grade gasoline also just simple physics mix, additive and petroleum naphtha mixed by weight 25～40: 60～75 get final product.Petroleum naphtha and binder component have mutual solubility, do not need the physics powerful mixing.
Nitromethane 99Min. in the additive can improve the combustion heat value of petroleum naphtha, can increase petroleum naphtha incendiary power effect during use, and can boosting of octane rating; Methyl alcohol can improve the oxygen level and the octane value of petroleum naphtha, thereby a large amount of suctions that can reduce when burning freezing air influence the effect of power; Kinematic behavior when pimelinketone can improve the petroleum naphtha burning makes running of an engine steady, reduces the colloid of oil fuel and the carbon deposit that engine is produced; Monoethanolamine MEA BASF has the flavor of taking off, deodorization, froth breaking and stabilization, the acid number of oil fuel is not gone up, not color reversion, limpid transparent, stay in grade; Ethylene glycol monomethyl ether can improve the solvability between petroleum naphtha and Nitromethane 99Min., methyl alcohol, pimelinketone and the Monoethanolamine MEA BASF, improves the uniformity coefficient and the stability of fuel, makes the product of producing reach the high-grade gasoline standard.
Petroleum naphtha can be the petroleum naphtha of research octane number (RON) between 48～65.The petroleum naphtha octane value that for example the petroleum naphtha octane value produced of grand celebration is 50, Tianjin produces is 65.Height according to the petroleum naphtha octane value can suitably be transferred additivated consumption, and petroleum naphtha a small amount of additive that adds in above-mentioned weight ratio scope that octane value is high just can obtain standard compliant high-grade gasoline,
Petroleum naphtha volume in above-mentioned weight ratio scope that octane value is low adds additive, can obtain standard compliant high-grade gasoline.
Additive provided by the invention can not need hydrogenation just can utilize petroleum naphtha to produce high-grade gasoline, and not have three wastes generation under normal temperature and pressure conditions, and additive raw material component cost is low, and making method is simple and safe.The high-grade gasoline that utilizes petroleum naphtha adding additive to obtain can meet the national standard of high-grade gasoline, can substitute existing high-grade gasoline fully and use.The raw material resources of this high-grade gasoline are extensive simultaneously, and are with low cost, and preparation process does not need High Temperature High Pressure and hydrogenation unit, and just simple physics is mixed, and is simple and safe.This additive can be used for petroleum naphtha and is mixed with the high high-grade gasoline of added value, and this high-grade gasoline can substitute existing high-grade gasoline and use.
